VENTlLATlNG-SH UTTER.

SPECIFICATION forming part of Letters Patent No. 424,015, dated March25, 1890.

Application filed August 31,1889. Serial No. 322,586. (No model.)

To all whom it may concern:

Be it known that I, MYRoN E. MOORE, a citi zen of the United States,residing at Deering Centre, in the county of Cumberland and State ofMaine, have invented a new and useful Operating Device forVentilating-Shutters, of which the following is a specification.

This invention has relation to operating devices for opening and closingventilatingshutters for cars and coaches; and among the objects in vieware to provide for a simultaneous opening or closing of the entireseries of shutters, and that by a cheap and economical construction.

The invention consists in certain features of construction, hereinafterspecified, and particularly pointed out in the claim.

Referring to the drawings, Figure 1 is a perspective of the interior ofthe sides of the car provided with ventilating-shutters and operatingdevices therefor constructed in accordance with my invention. Fig. 2 isa transverse section with dotted lines showing the shutter closed. Fig.3 is a detail in perspective of a section of the rock-shaft and rockarm.

Like numerals of reference indicate like parts in all the figures.

1 represents the side of the car or coach, and 2 a series of openingsfor the purpose of ventilation, and in the same are mounted pivotallythe shutters 3, the lower edges of which abut against beads 4, locatedupon the sills of the openings, whereby the bottom rail of the shutteris prevented from inward swing beyond the bead.

5 represents brackets secured along the side of the upright intermediateof each of the shutters, said brackets terminating at their upper endsin bearing-eyes 6, the entire series being In the bearing-eyes 6 isloosely journaled a rock-shaft 7, the ends of which outside of thebearings are dropped to form handles 8 for operating the shaft.

Mounted upon the shaft and at such points thereof as occur opposite thecenter of each shutter are rock arms 9, in this instance formed of lightsheet metal, the inner ends of which are bent to form an eye forreceiving the rod, as at 10, and are bolted by bolts 11 rigidly upon therod, so as to move therewith. The outer ends of the rock-arms are bentto form eyes 11*, and form one member of a hinge joint, the oppositemember of the joint being formed by the inner ends of links 12, whichare bent to form eyes 13, aligning with the eyes 11*, and through thesame is passed a pintle 14.

15 represents a hinge-leaf with which each of the shutters are providedbelow their pivots, said leaf having a pair of eyes 15*, which alignwith an eye 16*, formed on the outer end of each of the links, andthrough the same are passed pintles 16. Screwsl? connect thehinge-leaves to the shutters, and it will be apparent that by raisingthedrophandles of the rock-shaft and by reason of the hinged connectionsdescribed the shutters will be swung to an open position, as shown inFig. 2, the rock-arms and their respective links being brought into linewith each other and forming a rigid brace for supporting the shutters.By lowering the drop handles the rock-shaft will be partially rotated inan opposite direction, and the rockarms and their links folded, as shownby dotted lines in Fig. 2. It is also apparent that by operating thehandles described all of the shutters will be simultaneously operated.If desired, however, I may use a series of rockshafts each terminatingin handles and each governing and operating a certain number-ofshutters, thereby opening and closing a section, say, of three or fourshutters at one time, and thus cooling or warming the atmosphere inaccordance with the desires of passengers located in the vicinity of therespective sections.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

The combination, with the side of a car having a series ofventilating-openings and pivoted shutters mounted in the openings, of aseries of brackets secured to the car and terminating at their oppositeends in bearings, a rock-shaft mounted in the bearings and terminatingin handles, and a series of rock-arms, the lower ends of which are bentto embrace and bolted to the rock-shaft opposite each of the shutters,and having their outer ends bent to form one member of a hinge-joint,links for each of the rock-arms having their inner ends bent to form theopposite member of the joint, and pintles for connecting said members,and hinge-leaves secured to each of the shutters near their lower endand terminating in eyes forming one member of the hinge-joint andaligning 10 with an eye upon the outer ends of the links and pintles forinsert-ion through the same, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two Witnesses.
